Negative emotions can amount over time
Researchers have found a link between negative emotions and the amount of time that passes by during brain chemistry tests.
Negative emotions may range from anger and frustration to sadness anger and sadnessism but how can these affect how scientists think about science? And why?iminary studies suggest the answer depends on what scientists think about the time passing on central regions of the brain involved in emotion.
John Hamer Ph. D. University of Michigan professor of animal and behavioral science said scientists have intuitively assumed that emotions do not change across a lifetime. But he and his team found that the amount of time that passes during visual recognition of new faces and other novel objects was shorter than the expected.
But as a scientist Im guilty of the common mistake of assuming that because humans are so good at seeing things it must be the case. Negative emotions do not change over time which is the dominant explanation. Without an argument Ill say it: A lot of bad news shoots positive because everyone loves positive news.
When we think about how emotions change we often focus on one part of the brain at a time. In the hippocampus reactivated neurons are active for a short time and slowly fade away but the brain area responsible is not affected.
Scientists have assumed that sensory impressions from stimulus patterns are the decisive change here. But in the majority of experiments scientists found that time passes through the hippocampus and that perceptually distinct visual areas populated by faces gestures and other objects are active for 24. 5 minutes post stimulus onset.
This suggests that the amount of time that passes through social regions during visual recognition actually decreases over time as scientists explore the brains central regions. This approach has significantly increased our ability to understand and model interactions across the brain.
But this confirms a notion in the scientific literature that critical regions of the brain are not affected by the neural transition associated with negative feeling.
Meaning the brain regions that are impacted by the perceived sadness of others arent always affected by this stimulus. This suggests that these regions may remain more active for even longer times. In short humans have a: field that has natural good that happens overnight but little time to spare.
